STRUCTURAL-PROPERTIES OF AMORPHOUS BULK FE, CO AND FE-CO BINARY-ALLOYS

Elastic neutron diffraction experiments on amorphous iron, cobalt and their amorphous binary metallic alloys are presented. The measurements allow, and for the first time, to describe the atomic distribution in samples obtained in the form of fine (<30 nm) amorphous elemental par ticles by sonochemical synthesis. In the case of a-Fe, the structural information from the shape of the radial distribution function is cons istent with the Random Packing model (RPD) calculations previously mad e for films of amorphous iron. Finally the atomic magnetic moment of i ron and cobalt in the amorphous bulk phase is also evaluated.
